The radio communication unit 110 may include at least one module thatenables radio communication between the mobile terminal 100 and a radiocommunication system or between the mobile terminal 100 and a network inwhich the mobile terminal 100 is located. For example, the radiocommunication unit 110 may include a broadcasting receiving module 111,a mobile communication module 112, a wireless Internet module 113, alocal area communication module 114 (or short-range communicationmodule), and a position-location information module 115.

The broadcasting receiving module 111 may receive broadcasting signalsand/or broadcasting related information from an external broadcastingmanagement server through a broadcasting channel. The broadcastingchannel may include a satellite channel and a terrestrial channel, andthe broadcasting management server may be a server that generates andtransmits broadcasting signals and/or broadcasting related informationor a server that receives previously created broadcasting signals and/orbroadcasting related information and transmits the broadcasting signalsand/or broadcasting related information to a terminal.

The broadcasting signals may include not only TV broadcasting signals,radio broadcasting signals, and data broadcasting signals but alsosignals in the form of a combination of a TV broadcasting signal and aradio broadcasting signal. The broadcasting related information may beinformation on a broadcasting channel, a broadcasting program or abroadcasting service provider, and may be provided even through a mobilecommunication network. In the latter case, the broadcasting relatedinformation may be received by the mobile communication module 112.

The broadcasting related information may exist in various forms. Forexample, the broadcasting related information may exist in the form ofan electronic program guide (EPG) of a digital multimedia broadcasting(DMB) system or in the form of an electronic service guide (ESG) of adigital video broadcast-handheld (DVB-H) system.

The broadcasting receiving module 111 may receive broadcasting signalsusing various broadcasting systems. More particularly, the broadcastingreceiving module 111 may receive digital broadcasting signals usingdigital broadcasting systems such as a digital multimediabroadcasting-terrestrial (DMB-T) system, a digital multimediabroadcasting-satellite (DMB-S) system, a media forward link only(MediaFLO) system, a DVB-H and integrated services digitalbroadcast-terrestrial (ISDB-T) systems. The broadcasting receivingmodule 111 may receive signals from broadcasting systems providingbroadcasting signals other than the above-described digital broadcastingsystems.

The broadcasting signals and/or broadcasting related informationreceived through the broadcasting receiving module 111 may be stored inthe memory 160. The mobile communication module 112 may transmit/receivea radio signal to/from at least one of a base station, an externalterminal and a server on a mobile communication network. The radiosignal may include a voice call signal, a video telephony call signal ordata in various forms according to transmission and reception oftext/multimedia messages.

The position-location information module 115 may confirm or obtain aposition of the mobile terminal 100. The position-location informationmodule 115 may obtain position information by using a global navigationsatellite system (GNSS). The GNSS is a terminology describing a radionavigation satellite system that revolves around the earth and transmitsreference signals to predetermined types of radio navigation receiverssuch that the radio navigation receivers can determine their positionson the earth's surface or near the earth's surface. The GNSS may includea global positioning system (GPS) of the United States, Galileo ofEurope, a global orbiting navigational satellite system (GLONASS) ofRussia, COMPASS of China, and a quasi-zenith satellite system (QZSS) ofJapan, for example.

A global positioning system (GPS) module is a representative example ofthe position-location information module 115. The GPS module 115 maycalculate information on distances between one point or object and atleast three satellites and information on a time when a distanceinformation is measured and apply trigonometry to the obtained distanceinformation to obtain three-dimensional position information on thepoint or object according to latitude, longitude and altitude at apredetermined time.

A method of calculating position and time information using threesatellites and correcting a calculated position and time informationusing another satellite may also be used. Additionally, the GPS module115 may continuously calculate the current position in real time andcalculate velocity information using location or position information.

As shown in FIG. 1, the A/V input unit 120 may input an audio signal ora video signal and include a camera 121 and a microphone 122. The camera121 may process image frames of still images or moving images obtainedby an image sensor in a video telephony mode or a photographing mode.The processed image frames may be displayed on a display 151, which maybe a touch screen.

The image frames processed by the camera 121 may be stored in the memory160 or may be transmitted to an external device through the radiocommunication unit 110. The mobile terminal 100 may also include atleast two cameras 121.

The microphone 122 may receive an external audio signal in a call mode,a recording mode or a speech recognition mode and process the receivedaudio signal into electric audio data. The audio data may then beconverted into a form that can be transmitted to a mobile communicationbase station through the mobile communication module 112 and output inthe call mode. The microphone 122 may employ various noise removalalgorithms (or noise canceling algorithm) for removing or reducing noisegenerated when the external audio signal is received.

The user input unit 130 may receive input data for controlling operationof the mobile terminal 100 from a user. The user input unit 130 mayinclude a keypad, a dome switch, a touch pad (constantvoltage/capacitance), a jog wheel, a jog switch and/or so on.

The sensing unit 140 may sense a current state of the mobile terminal100, such as an open/close state of the mobile terminal 100, a positionof the mobile terminal 100, whether a user touches the mobile terminal100, a direction of the mobile terminal 100, andacceleration/deceleration of the mobile terminal 100, and generate asensing signal for controlling operation of the mobile terminal 100. Forexample, in an example of a slide phone, the sensing unit 140 may sensewhether the slide phone is opened or closed. Further, the sensing unit140 may sense whether the power supply 190 supplies power and/or whetherthe interface 170 is connected to an external device. The sensing unit140 may also include a proximity sensor 141.

The output unit 150 may generate visual, auditory and/or tactile outputand may include the display 151 (or display module), an audio outputmodule 152, an alarm 153 (or alarm module) and a haptic module 154. Thedisplay 151 may display information processed by the mobile terminal100. The display 151 may display a user interface (UI) or a graphic userinterface (GUI) related to a telephone call when the mobile terminal 100is in the call mode. The display 151 may also display a captured and/orreceived image, a UI or a GUI when the mobile terminal 100 is in thevideo telephony mode or the photographing mode.

Additionally, the display 151 may include at least one of a liquidcrystal display, a thin film transistor liquid crystal display, anorganic light-emitting diode display, a flexible display and athree-dimensional display. Some of these displays may be of atransparent type or a light transmissive type. That is, the display 151may include a transparent display.

The transparent display may include a transparent liquid crystaldisplay. The rear structure of the display 151 may also be of a lighttransmissive type. Accordingly, a user may see an object located behinda body of the mobile terminal 100 through the transparent area of thebody of the mobile terminal 100 that is occupied by the display 151.

The mobile terminal 100 may also include at least two displays 151. Forexample, the mobile terminal 100 may include a plurality of displays 151that are arranged on a single face at a predetermined distance orintegrated displays. The plurality of displays 151 may also be arrangedon different sides.

Further, when the display 151 and a sensor sensing touch (hereafterreferred to as a touch sensor) form a layered structure that is referredto as a touch screen, the display 151 may be used as an input device inaddition to an output device. The touch sensor may be in the form of atouch film, a touch sheet, and/or a touch pad, for example.

The touch sensor may convert a variation in pressure applied to aspecific portion of the display 151 or a variation in capacitancegenerated at a specific portion of the display 151 into an electricinput signal. The touch sensor may sense pressure of touch as well asposition and area of the touch.

When the user applies a touch input to the touch sensor, a signalcorresponding to the touch input may be transmitted to a touchcontroller. The touch controller may then process the signal andtransmit data corresponding to the processed signal to the controller180. Accordingly, the controller 180 may detect a touched portion of thedisplay 151.

The proximity sensor 141 of the sensing unit 140 may be located in aninternal region of the mobile terminal 100, surrounded by the touchscreen, and/or near the touch screen. The proximity sensor 141 may sensean object approaching a predetermined sensing face or an object locatednear the proximity sensor using an electromagnetic force or infraredrays without having mechanical contact. The proximity sensor 141 mayhave a lifetime longer than a contact sensor and may thus have a wideapplication in the mobile terminal 100.

The proximity sensor 141 may include a transmission type photo-electricsensor, a direct reflection type photo-electric sensor, a mirrorreflection type photo-electric sensor, a high-frequency oscillatingproximity sensor, a capacitive proximity sensor, a magnetic proximitysensor, and/or an infrared proximity sensor. A capacitive touch screenmay be constructed such that proximity of a pointer is detected througha variation in an electric field based on the proximity of the pointer.The touch screen (touch sensor) may be classified as a proximity sensor141.

For ease of explanation, an action of the pointer approaching the touchscreen without actually touching the touch screen may be referred to asa proximity touch and an action of bringing the pointer into contactwith the touch screen may be referred to as a contact touch. Theproximity touch point of the pointer on the touch screen may correspondto a point of the touch screen at which the pointer is perpendicular tothe touch screen.

The proximity sensor 141 may sense the proximity touch and a proximitytouch pattern (e.g., a proximity touch distance, a proximity touchdirection, a proximity touch velocity, a proximity touch time, aproximity touch position, a proximity touch moving state, etc.).Information corresponding to the sensed proximity touch action andproximity touch pattern may then be displayed on the touch screen.

The audio output module 152 may output audio data received from theradio communication unit 110 or stored in the memory 160 in a callsignal receiving mode, a telephone call mode or a recording mode, aspeech recognition mode and a broadcasting receiving mode.

The audio output module 152 may include areceiver, a speaker, a buzzer, and/or the like. The audio output module152 may output sounds through an earphone jack. The user may hear thesounds by connecting an earphone to the earphone jack.

The alarm 153 may output a signal for indicating generation of an eventof the mobile terminal 100. For example, alarms may be generated whenreceiving a call signal, receiving a message, inputting a key signal,and/or inputting touch. The alarm 153 may also output signals in formsdifferent from video signals or audio signals, for example, a signal forindicating generation of an event through vibration. The video signalsor the audio signals may also be output through the display 151 or theaudio output module 152.

The haptic module 154 may generate various haptic effects that the usermay feel. One example of the haptic effects is vibration. Intensityand/or pattern of vibration generated by the haptic module 154 may alsobe controlled. For example, different vibrations may be combined andoutput and/or may be sequentially output.

The haptic module 154 may generate a variety of haptic effects includingan effect of stimulus based on an arrangement of pins vertically movingagainst a contact skin surface, an effect of stimulus according to a jetforce or sucking force of air through a jet hole or a sucking hole, aneffect of stimulus of rubbing the skin, an effect of stimulus based oncontact of an electrode, an effect of stimulus using an electrostaticforce, and an effect based on a reproduction of cold and warmth using anelement capable of absorbing or radiating heat in addition tovibrations.

As shown in FIG. 3, when a pointer such as a user's finger approachesthe touch screen, the proximity sensor located inside or near the touchscreen senses the approach and outputs a proximity signal.

The proximity sensor may be constructed such that it outputs a proximitysignal based on a distance between the pointer approaching the touchscreen and the touch screen (referred to as a proximity depth).

The distance in which the proximity signal is output when the pointerapproaches the touch screen may be referred to as a detection distance.The proximity depth may be known by using a plurality of proximitysensors having different detection distances and comparing proximitysignals respectively output from the proximity sensors.

FIG. 3 shows a section of the touch screen in which proximity sensorscapable of sensing three proximity depths are provided. Proximitysensors capable of sensing less than three or more than four proximitydepths may be provided in the touch screen.

More specifically, when a pointer completely comes into contact with thetouch screen (D0), it may be recognized as a contact touch. When thepointer is located within a distance D1 from the touch screen, it may berecognized as a proximity touch of a first proximity depth. When thepointer is located in a range between the distance D1 and a distance D2from the touch screen, it may be recognized as a proximity touch of asecond proximity depth. When the pointer is located in a range betweenthe distance D2 and a distance D3 from the touch screen, it may berecognized as a proximity touch of a third proximity depth. When thepointer is located greater than the distance D3 from the touch screen,it may be recognized as a cancellation of a proximity touch.

Accordingly, the controller 180 may recognize the proximity touch asvarious input signals based on the proximity distance and proximityposition of the pointer with respect to the touch screen, and thecontroller 180 may perform various operation controls based on the inputsignals.

The wallpaper W may display the widget icons WD and the icons I basedon whether or not information may be dynamically displayed throughicons. For example, a first widget icon WD1 may correspond to time andweather widgets. The controller 180 may change the display of the firstwidget icon WD1 based on a lapse of time and/or based on a weathervariation. The icons I may function as media for executing specificapplications. For example, if a music icon is selected, a playerapplication capable of playing mp3 may be executed. Additionally, if asubway icon is selected, an application capable of displaying a subwaytimetable may be executed. The widget icons WD and the icons I may berepresented as the objects OB in the following description exceptadditionally marked parts.

Positions and space widths of the objects OB may depend on theirattributes. That is, a display form of each object OB may vary based onthe attribute thereof. For example, when the user wants to display thefirst widget icon WD1 having a large size on the wallpaper W, thewallpaper W may be required to have a space capable of accommodating thefirst widget icon WD1. If the wallpaper W does not have the space, thefirst widget icon WD1 may not be located on the wallpaper W. In thisexample, it may be required to delete other objects OB located on thewallpaper W or generate a new wallpaper to create space for displayingthe first widget icon WD1.

Multiple wallpapers W may exist. That is, there may be multiplewallpapers W capable of displaying the objects OB. For example, thewallpaper W shown in FIG. 5 may correspond to a first wallpaper W1 andother wallpapers W that are not shown in FIG. 5 may exist. The user maydrag or flick the display 151 to the left or to the right to display awallpaper W on the left or the right of the first wallpaper W1 on thedisplay 151.

After the wallpaper W is displayed on the display 151, an event ofadding an object OB to the wallpaper W may be performed in operationS20. This may also be referred to as an event of adding an object.

The adding of the object OB to the wallpaper W may be performed orinitiated by a user's input or a control operation of the controller180. For example, the user may touch a virtual button B displayed on thedisplay 151 to add the object OB to the wallpaper W. As shown in FIG. 6,when the user touches the virtual button B displayed on the display 151,the controller 180 may display icons I that can be added to thewallpaper W on the display 151. The user can touch one of the displayedicons I to add the touched icon I to the wallpaper W. The adding of theobject OB to the wallpaper W may be explained in more detail later.

When an event of adding of the object OB to the wallpaper W isperformed, multiple wallpapers W may be displayed on the display 151 inoperation S30.

When an event of adding of the object OB to the wallpaper W isperformed, the controller 180 may determine whether or not the wallpaperW currently displayed on the display 151 has a vacancy. If the currentlydisplayed wallpaper W does not have the vacancy, multiple wallpapers Wmay be displayed on the display 151. For example, the first wallpaper W1currently displayed on the display 151 may not have a vacancy fordisplaying the added object OB because the first wallpaper W1 includesthe widget icons WD and the icons I, as shown in FIG. 5. In thisexample, the controller 180 may display another wallpaper W capable ofdisplaying the added object OB on the display 151 to show the wallpaperW to the user. To secure a space for displaying the other wallpaper W onthe display 151, the controller 180 may reduce an area of the firstwallpaper W1 currently displayed on the display 151. The controller 180may display the other wallpaper W in the space secured by reducing thearea of the first wallpaper W1.

When the multiple wallpapers W are displayed on the display 151, theadded object OB may be located (or provided) in a specific position onthe multiple wallpapers W in operation S40.

At least one of the displayed wallpapers W may have a vacancy such thatthe wallpaper is capable of displaying the added object OB. The user mayadd the object OB to the wallpaper W having the vacancy by using a touchoperation. If the displayed wallpapers W do not have a vacancy capableof displaying the added object Oft the user may touch (or touch anddrag) the display 151 to the left or to the right to search for awallpaper W having a vacancy such that the wallpaper is capable ofdisplaying the added object OB. As described above, the size and/or theshape of the object OB may depend on its attribute. For example, aspecific object may have a size of 16×16 while another object may have asize of 32×32.

FIG. 7 is a flowchart of the operation S30 of displaying multiplewallpapers on the display 151, as shown in FIG. 4. FIG. 8 is a view forexplaining the operation of the mobile terminal 100, as shown in FIG. 7.Other embodiments may also be provided.

As shown in FIGS. 7 and 8, the operation S30 of displaying multiplewallpapers W on the display 151 may include an operation S31 of reducingan area of the currently displayed wallpaper W.

As described above, the controller 180 may display multiple wallpapers Won the display 151 when the currently displayed wallpaper W does nothave a vacancy capable of displaying the added object OB. To display themultiple wallpapers W on the display 151, a space for displaying themultiple wallpapers W may have to be secured. The controller 180 mayreduce the area of the wallpaper W displayed on the overall area of thedisplay 151 to secure the space for displaying the multiple wallpapersW. For example, when the event of adding the object OB to the wallpaperW is performed while the first wallpaper W1 is displayed on the overallarea of the display 151, the controller 180 may reduce the area of thefirst wallpaper W. Then, the controller 180 may display second, third,fourth and fifth wallpapers W2, W3, W4 and W5 in the space secured byreducing the first wallpaper W1.

When the wallpaper W is reduced, the controller 180 may displaywallpaper indicators WI on the display 151. The wallpaper indicators WImay correspond to respective wallpapers W. For example, when the usergenerates seven wallpapers, seven wallpaper indicators may be displayedon the display 151. However, only five of the seven wallpapers W aredisplayed on the display 151 (in FIG. 8) due to a restriction on thearea of the display 151.

When the currently displayed wallpaper W is reduced, an activatedwallpaper W may be located at a center of the display 151 in operationS32.

The activated wallpaper W may correspond to a wallpaper W that wasdisplayed on the display 151 before the currently displayed wallpaper isreduced. The activated wallpaper may be a wallpaper displayed at acenter of the display 151 by touching the reduced wallpaper W. Forexample, the activated wallpaper W may correspond to the first wallpaperW1, as shown in FIG. 8. The wallpaper indicators WI may indicate thecurrently activated wallpaper W. That is, the wallpaper indicator WIcorresponding to the first wallpaper W1 may be indicated differentlyfrom the other six wallpaper indicators WI when the first wallpaper W1is activated, as shown in FIG. 8. The activation may be different fromactivation when there is a vacancy such that the wallpaper is capable ofdisplaying an object Oft as may be described below. That is, activationin operation S32 may represent that the activated wallpaper W can bedisplayed on the display 151 when the operation of displaying thewallpaper W on the overall area of the display 151 is performed.

Subsequently, the regions occupied by objects OB may be darkened inoperation S33.

Various objects OB in addition to an icon I that the user wants to newlyadd may be provided on the wallpaper W. Accordingly, a certainwallpaper, such as the first and fourth wallpapers W1 and W4, may nothave a vacancy for displaying an added object OB. A certain wallpaper,such as the second wallpaper W2, may have an object OB located thereon.In this example, the new object OB may not be added to the secondwallpaper W2. Accordingly, the controller 180 may inactivate regionswhere objects have been arranged and may make the inactivated regionsdarker so as to visually represent the inactivated regions.

The controller 180 may determine whether or not the wallpaper W has avacancy capable of displaying the added object OB in operation S34 andgenerate a new wallpaper W when the wallpaper W does not have thevacancy in operation S35.

The wallpaper W may not have the vacancy capable of displaying the addedobject OB. For example, when two wallpapers are currently displayed onthe display 151 and objects OB are located over the two wallpapers, thecontroller 180 may add a new wallpaper for displaying the added objectOB.

When the wallpaper W has the vacancy for displaying the added object Oftthe vacancy for displaying the added object OB may be displayed inoperation S36.

The wallpaper W may have a vacancy in which an object OB may beadditionally provided. For example, the second wallpaper W2 may have avacancy V, as shown in FIG. 8. The controller may display the vacancy Vbrighter to visually inform the user that the second wallpaper W2 hasthe vacancy V. The controller 180 may further indicate a boundary linealong the outline of the vacancy V.

FIGS. 9 and 10 illustrate implementations of adding an object towallpaper. Other embodiments may also be provided.

Referring to FIGS. 9 and 10, the mobile terminal 100 may add an objectOB to the wallpaper W in various manners.

As shown in FIG. 9 (a), when the user touches the virtual button B,icons I that may be added are displayed on the display 151. The user mayselect a first icon I1 to be added from the displayed icons I bytouching the first icon I1 with a finger F (or other pointing device).The user may drag the selected first icon I1 in a specific direction.

As shown in FIG. 9 (b), when the user selects the first icon I1 anddrags the selected first icon I1, a first menu screen MW, on which theicons I are displayed, may slide (or be provided) to a bottom of thedisplay 151. The first wallpaper W1 may then be displayed on a spacecreated by sliding (or providing) of the first menu screen MW. Further,the user may continuously touch the first icon I1 to move the first iconI1 from the first menu screen MW to the first wallpaper W1. AlthoughFIG. 9 shows movement of the first icon I1 from the first menu screen MWto the first wallpaper W1, the above touch-and-drag method may beapplied to an example that an icon I located on a specific wallpaper ismoved to another wallpaper.

As shown in FIG. 10 (a), the user may long touch, with a finger F, avacancy of the display 151 in which any object OB is not located.Additionally, the user may press a specific button MB (i.e., a menubutton).

As shown in FIG. 10 (b), when the user long touches the vacancy of thedisplay 151 or presses the specific button MB, the controller 180 maydisplay a second menu screen ME on the display 151. The user may selecta widget icon or an icon from the second menu screen ME or its lowermenu to add the selected icon to the wallpaper W.

FIGS. 11, 12 and 13 are views for explaining an operation of the mobileterminal 100, as shown in FIG. 4. Other embodiments may also beprovided.

Referring to FIGS. 11, 12 and 13, the mobile terminal 100 may displayreduced wallpapers W on the display 151 such that the user mayintuitively select a wallpaper on which an added icon may be located.

Referring to FIG. 11 (a), the first wallpaper W1 may display variousobjects OB. The user may perform an event of adding an object. Forexample, the user may touch the virtual button B and/or press thespecific button MB to start the event.

Referring to FIG. 11 (b), when the event is started, a size of the firstwallpaper W1 displayed on an overall area of the display 151 may bereduced. The controller 180 may display the first wallpaper W1 as acontinuously decreasing object such that the user may be interested inoperation of the mobile terminal 100. The display 151 may display thefirst icon I1 selected by the user.

As shown in FIG. 11 (c), the second, third, fourth and fifth wallpapersW2, W3, W4 and W5 may be displayed in an area obtained by reducing thefirst wallpaper W1. Further, the wallpaper indicators WI that indicatethe currently activated wallpapers W may be displayed at the upper partof the display 151. The controller 180 may display a vacancy V in thedisplayed wallpaper W, in which the added first icon I1 may be located.That is, the controller 180 may inactivate an area where the first iconI1 may not be located due to objects OB that occupy the area to make thearea darker and activate an area where any object OB is not located andthus the first icon I1 may be displayed to make the area brighter.

As shown in FIG. 12 (a), the user may select the first icon I1 and dragthe selected first icon I1 to the vacancy V. Then, the first icon I1 islocated on the second wallpaper W2, as shown in FIG. 12 (b).

As shown in FIG. 12 (c), the controller 180 may display the secondwallpaper W2 including the first icon I1 added by the user at a centerof the display 151.

As shown in FIG. 12 (d), the controller 180 may enlarge the secondwallpaper W2 including the first icon I1 and display the secondwallpaper W2 on the display 151. That is, the second wallpaper W2 may beenlarged and displayed on an overall area of the display 151. Thecontroller 180 may display the second wallpaper W2 as a continuouslyincreasing object such that the user may be interested in operation ofthe mobile terminal 100.

As shown in FIG. 13, the enlarged second wallpaper W2 including thefirst icon I1 is displayed on an overall area of the display 151.

FIGS. 14 through 18 are views for explaining an operation of the mobileterminal 100 to add an icon, as shown in FIG. 4.

The mobile terminal 100 may add an icon I to the wallpaper W in variousmanners.

As shown in FIG. 14 (a), the display 151 may display the first wallpaperW1 and the second wallpaper W2. Since two wallpaper indicators WI aredisplayed on the display 151, a total number of wallpapers equals two(i.e., the first and second wallpapers W1 and W2). An icon I to be addedmay be displayed in a region of the display 151 that does not correspondto the first wallpaper W1 and the second wallpaper W2.

As shown in FIG. 14 (b), the controller 180 may display a thirdwallpaper W3 as a new wallpaper. The currently displayed first wallpaperW1 and the second wallpaper W2 include objects Oft and thus the firstwallpaper W1 and the second wallpaper W2 do not have a vacancy fordisplaying the icon I selected by the user. Accordingly, the controller180 may generate the third wallpaper W3 to additionally display the iconI. The third wallpaper W3 may be a newly generated, and thus the thirdwallpaper W3 may not include an object OB. Accordingly, the user may addthe icon I, a new object Oft to the third wallpaper W3.

As shown in FIG. 15 (a), the user may want to add an icon I having aspecific shape and size to the wallpaper W. The controller 180 maydisplay a space for displaying the added icon I based on the shape andsize of the icon I. For example, the controller 180 may inactivate theoverall area of the third wallpaper W3 that is occupied by objects OBand may have no vacancy for displaying the icon I. The second wallpaperW2 may have a first vacancy V1 that is not occupied by an object OB.However, the icon I may not be fitted in the first vacancy V1 because ofits shape and size. Accordingly, the controller 180 may also inactivatethe overall area of the second wallpaper W2. The first wallpaper W1 mayhave a second vacancy V2 that is not occupied by an object OB. Further,the second vacancy V2 may have a shape and a size suitable for the shapeand the size of the icon I. Accordingly, the controller 180 may activatethe second vacancy V2 in the first wallpaper W1 and inactivate theremaining part of the first wallpaper W1. That is, the controller 180may display the area where the added icon I may be located such that thearea is discriminated from other areas to improve ease of use.

As shown in FIG. 15 (b), the controller 180 may display an appropriatevacancy V in consideration of the size of an icon I to be added.

As shown in FIG. 16 (a), the second wallpaper W2 (from among the first,second and third wallpapers W1, W2 and W3) may not have a vacancy fordisplaying the added icon I. Accordingly, the controller 180 mayactivate a second vacancy V2 and a third vacancy V3 in which the icon Imay be located and may inactivate other areas.

As shown in FIG. 16 (b), the controller 180 may display only a wallpaperW having a vacancy for displaying an icon I. More specifically, thesecond wallpaper W2 may not have an appropriate space in FIG. 16 (a),and thus the controller 180 may display only the first wallpaper W1 andthe third wallpaper W3 on the display 151.

As shown in FIG. 17, the controller 180 may change the display ofwallpaper indicators WI such that the user may be intuitively aware ofan appropriate location for displaying an icon I. The wallpaperindicators WI respectively correspond to wallpapers W, as describedabove. Accordingly, the controller 180 may change the display of thewallpaper indicators WI respectively corresponding to wallpapers toinform the user of a wallpaper having a vacancy for displaying the addedicon I. For example, the third wallpaper indicator W13 and the seventhwallpaper indicator W17 may have a shape different from other wallpaperindicators, as show in FIG. 17. The third wallpaper indicator W13 havinga shape different from others may represent that the third wallpaper W3corresponding to the third wallpaper indicator W13 has a vacancy V2 fordisplaying the icon I. Further, a seventh wallpaper corresponding to theseventh wallpaper indicator W17 may have a vacancy for displaying theicon I, which is not shown in FIG. 17. That is, even when all thewallpapers may not be displayed due to a physical size limit of thedisplay 151, a wallpaper having a vacancy may be indicated by thewallpaper indicator corresponding thereto, which may improve the ease ofuse.

FIG. 18 (a) illustrates an order of adding icons to the wallpaper W. Asshown in FIG. 18 (a), the icons may be arranged from an upper part X1 toa lower part X4 when the user does not designate specific positions.Additionally, the icons may be arranged from the left to the right on asame line.

As shown in FIG. 18 (b), the first icon I1 may be located on thewallpaper W. When the second icon I2 is added to the wallpaper W (thatincludes the first icon I1), the second icon I2 may be located on theright of the first icon I1. As shown in FIG. 18 (c), when the first andsecond icons I1 and I2 are arranged on the first line of the wallpaperW, the third icon I3 may be located on the left of a second line. Thatis, the icons may be arranged from the top left of the wallpaper to thebottom right of the wallpaper.

The above-described method of controlling the mobile terminal may bewritten as and/or include computer programs and may be implemented indigital microprocessors that execute programs using a computer readablerecording medium. The method of controlling the mobile terminal may beexecuted through software. The software may include code segments thatperform required tasks. Programs or code segments may also be stored ina processor readable medium or may be transmitted according to acomputer data signal combined with a carrier through a transmissionmedium or communication network.

The computer readable recording medium may be any data storage devicethat can store data that may be thereafter read by a computer system.Examples of the computer readable recording medium may include read-onlymemory (ROM), random-access memory (RAM), CD-ROMs, DVD±ROM, DVD-RAM,magnetic tapes, floppy disks, and/or optical data storage devices. Thecomputer readable recording medium may also be distributed over networkcoupled computer systems so that the computer readable code is storedand executed in a distribution fashion.

A mobile terminal may include a first touch screen to display a firstobject, a second touch screen to display a second object, and acontroller configured to receive a first touch input applied to thefirst object and to link the first object to a function corresponding tothe second object when receiving a second touch input applied to thesecond object while the first touch input is maintained.

A method may also include displaying a first object on the first touchscreen, displaying a second object on the second touch screen, receivinga first touch input applied to the first object, and linking the firstobject to a function corresponding to the second object when a secondtouch input applied to the second object is received while the firsttouch input is maintained.

FIG. 19 illustrates an operation of a mobile terminal according toanother embodiment and FIGS. 20 to 23 illustrate an operation of themobile terminal shown in FIG. 19.

As shown in FIGS. 19 to 23, the controller (180 of FIG. 1) of the mobileterminal 100 according to another embodiment may display wallpapers W onthe display 151 (S50).

Referring to FIG. 20, a first wallpaper W1 from among a plurality ofwallpapers W may be displayed on the display 151 of the mobile terminal100. The first wallpaper W1 may include objects OB. The objects OB mayinclude normal icons I and widget icons (WD of FIG. 5), as describedabove. In the following, the normal icons I are described anddescription of the widget icons (WD of FIG. 5) is omitted.

The objects OB may be moved (S60).

An operation of touching an object OB displayed on the display 151 mayinclude the following events. A first event may be an event of executingthe touched object OB. For example, when a first icon I1 located on thefirst wallpaper W1 is touched with a finger F and then short touchedwithin a short time, a function corresponding to the first icon I1 canbe executed. A second event may be an event of moving the touched objectOB. For example, when the first icon I1 located on the first wallpaperW1 is long touched, the mobile terminal 100 can enter a move mode inwhich the first icon I1 is moved to the first wallpaper W1 or otherwallpaper W. The function of the first icon I1 may not be executed inthe move mode. Accordingly, the user can move icons I by dragging thefirst icon I1 and other icons I. In the following, a touch point TPtouched by a finger F, instead of the finger F touching the display 151,is shown for convenience of understanding.

When the mobile terminal enters the icon move mode, the controller (180of FIG. 1) can reduce the area of a wallpaper W displayed on the display151, as shown in FIG. 21. That is, when long touch applied to the touchpoint TP is maintained for a predetermined time or longer, the area ofthe first wallpaper W1 is continuously reduced and thus a space can begenerated on the display 151.

Upon generation of an event of moving the object Oft a plurality ofwallpapers W may be displayed on the display 151 (S70).

Referring to FIG. 22, the plurality of wallpapers W may include firstwallpaper W1 having a reduced size, second and third wallpapers W2 andW3 respectively located on the left and right sides of the firstwallpaper W1. However, the number of plural wallpapers W displayed onthe display 151 is not limited thereto and the number and display formsof wallpapers W may be varied according to the resolution and/or size ofthe display 151.

The plurality of wallpapers W displayed on the display 151 may bechanged. For example, when the user drags the display to the left orright while maintaining the touch point TP with respect to the firsticon I1, a fourth wallpaper or a fifth wallpaper may be sequentiallydisplayed.

Upon display of the plurality of wallpapers W, a plurality of previewscreens Q may be displayed (S80).

The preview screens Q may be reduced images respectively correspondingto the plurality of wallpapers W. The preview screens Q can reflectstates of the wallpapers W on the screen of the display 151,distinguished from the plurality of wallpapers W. The preview screens Qbriefly show arrangement states of objects OB included in the wallpapersW. That is, the user can manipulate an object OB displayed on awallpaper W by touching the object OB whereas the user cannot manipulatea preview icon Q1 displayed on a preview screen Q even when the usertouches the preview icon Q1. As described above, the preview screens Qcan display the wallpapers W in a small size by showing only arrangementstate of objects OB included in the wallpapers W. Accordingly, thepreview screens Q can be less limited by the size and/or resolution ofthe display 151. For example, the preview screens Q can display statesof all wallpapers W while one to three wallpapers W are displayed. Thisis illustrated in FIG. 22. That is, the first, second and thirdwallpapers W1, W2 and W3 are displayed while first to fifth previewscreens Q1 to Q5 are displayed. Since the first to fifth preview screensQ1 to Q5 are displayed, it is not necessary to check the wallpapers Wone by one by moving the wallpapers W to the left or right.

A region in which an object OB can be located may be displayed in apreview screen Q. For example, a vacancy to which a selected object OBcan be moved may be displayed as a bright region and a region in whichan object OB cannot be located may be displayed as a dark region. InFIG. 22, the first, third, fourth and fifth preview screens Q1, Q3, Q4and Q5 that do not have a vacancy for displaying the first icon I1 areinactivated and displayed as dark regions and the second preview screenQ2 having a vacancy is activated and displayed as a bright region. Sincea vacancy to which the selected first icon I1 can be moved is displayedin a preview screen Q, the user of the mobile terminal 100 canintuitively recognize the position to which the first icon I1 can bemoved.

Upon display of the plurality of preview screens Q, a process of movingthe object OB may be displayed on a preview screen Q (S90).

The user can move the first icon I1 corresponding to an object OBdisplayed on the first wallpaper W1 to another wallpaper W. As shown inFIG. 22, the user can touch and drag the first icon I1 in a desireddirection while maintaining the touch point TP on the first icon I1.

When the first icon I1 is touched and moved, movement of the object OBcan be displayed on a preview screen Q. A shape corresponding to theobject OB displayed on the wallpaper W may be displayed on the previewscreen Q. For example, a first preview icon IQ1 corresponding to thefirst icon I1 displayed on the wallpaper W can be displayed on thepreview screen Q. When the first icon I1 is manipulated, manipulation ofthe first icon I1 can be reflected in the first preview icon IQ1. Forexample, if the user moves the first icon I1 from the initial positionthereof to the left of the display 151 by touching the first icon I1,the first preview icon IQ1 displayed on the preview screen Q can bemoved in the same direction. Referring to FIG. 22, when the first iconI1 located on the first wallpaper W1 is touched and dragged, the firstpreview icon IQ1 displayed on the first preview screen Q1 can be movedin the same direction. Deletion of the object OB can be performed in thesame manner. That is, upon deletion of the first icon I1, the firstpreview icon IQ1 can be deleted.

When the user moves the first icon I1 while touching the first icon I1,the preview screen Q can be changed according to movement of the firsticon I1. Referring to FIG. 23, when the user drags the first icon I1 tothe second wallpaper W2, the first preview icon IQ1 of the previewscreen W can be moved to the second preview screen Q2.

FIGS. 24 and 25 illustrate another operation of the mobile terminalshown in FIG. 19.

As shown in FIGS. 24 and 25, the mobile terminal 100 according to oneembodiment can move an icon I to a specific preview Q. Furthermore, uponmovement of the icon I to the specific preview screen Q, a previewpop-up window BP can be displayed. In the following, display of thewallpapers W and preview screens Q of the display 151 will be simplifiedfor easiness of understanding.

Referring to FIG. 24, the display 151 may display reduced wallpapers Wand preview screens Q. The user can move the first icon I1 displayed onthe first wallpaper W to a second preview screen Q2. The user can movethe first icon I1 to the second preview screen Q2 by selecting the firsticon I1 and dragging the first icon I1 to the second preview screen Q2.

Referring to FIG. 25, when the user drags and drops the first icon I1from the first wallpaper W1 to the second preview screen Q2, the previewpop-up window BP can be displayed. The preview pop-up window BP may bethe enlarged second preview screen Q2. As described above, since thesecond preview screen Q2 is small, the user may not directly manipulatethe preview icon (IQ of FIG. 23) displayed on the second preview screenQ2. However, the user may touch an icon I displayed on the previewpop-up window BP enlarged to be similar to the size of a wallpaper W.That is, the user can adjust icon arrangement by touching icons Idisplayed on the preview pop-up window BP. The preview pop-up window BPcan disappear when the user touches a region outside the preview pop-upwindow BO or the user touches an icon I and drags the touched icon I tothe outside of the preview pop-up window BP or after a lapse ofpredetermined time.

The same image as the wallpaper W corresponding to the preview pop-upwindow BP may be displayed on the preview pop-up window BP. For example,if the first wallpaper W1 displays a car, the preview pop-up window BPcan display the car. Since the preview pop-up window BP and thewallpaper W corresponding thereto display the same image, the user canarrange icons I in consideration of harmony with the image. For example,when the first icon I1 is black, the first icon I1 can be displayed suchthat the first icon I1 is not located in a black region.

FIG. 26 illustrates another operation of the mobile terminal shown inFIG. 19.

As shown in FIG. 26, the controller (180 of FIG. 1) of the mobileterminal 100 according to an embodiment can return an icon I to theinitial position thereof when the user locates the icon I in aninappropriate preview pop-up window BP. For example, the user may wantto locate the first icon I1 on a third preview screen Q3. However, thethird preview screen Q3 may not have a vacancy for displaying the firsticon I1. That is, the third wallpaper W3 corresponding to the thirdpreview screen Q3 has no appropriate space. In this case, when the userdrags the first icon I1 and drops the first icon I1 to the third previewscreen Q3, the controller (180 of FIG. 1) can return the first icon I1to the initial position thereof on the first wallpaper W1. Returning ofthe first icon I1 to the initial position on the first wallpaper W1 maybe displayed as if the first icon I1 is moving according to animationeffect.

FIGS. 27, 28 and 29 illustrate another operation of the mobile terminalof FIG. 19.

As shown in FIGS. 27, 28 and 29, the controller (180 of FIG. 1) of themobile terminal 100 according to an embodiment can combine previewscreens Q or wallpapers W or change the sequence of preview screens Q orwallpapers W. Since a preview screen Q reflects a wallpaper Wcorresponding thereto, when one of the preview screen Q and wallpaper Wis manipulated, the other can respond to the manipulation in the samemanner as the one of them. Accordingly, only manipulation of a previewscreen Q will be described in the following.

Referring to FIG. 27(a), first to fifth preview screens Q1 to Q5 may bedisplayed. A first preview icon IQ1 may be displayed on the firstpreview screen Q1 and second and third preview icons IQ2 and IQ3 may bedisplayed on the second preview screen Q2.

Referring to FIG. 27(b), the user may drag two preview screens Q in adirection in which the two preview screens Q become close to each other.For example, the user can touch the first preview screen Q1 with a firstfinger F1, touch the second preview screen Q2 with a second finger F2and drag the touches in a direction in which the touches become close toeach other. Upon dragging of the first and second preview screens Q1 andQ2, the selected preview screens Q can be combined.

Referring to FIG. 27(c), the second and third preview icons IQ2 and IQ3included in the second preview screen Q2 can be moved to the firstpreview screen Q1. Accordingly, the first, second and third previewicons IQ1, IQ2 and IQ3 can be displayed on the first preview screen Q1.

Referring to FIG. 28(a), the user can drag the second and third previewscreens Q2 and Q3 to the first preview screen Q1 using the first andsecond fingers F1 and F2.

Referring to FIG. 28(b), the second and third preview screens Q2 and Q3dragged by the first and second fingers F1 and F2 of the user can becombined with the first preview screen Q1.
